Reviews
Finally got to the bottom of the fault after two garages couldn't fix it. Brilliant service.
Came out within 24 hours. Diagnosed the fault on the spot and explained everything clearly.
No more countdown warning. Would highly recommend to anyone with AdBlue problems.

Questions about AdBlue diagnostics
Quick answers before you book.
What's the difference between a diagnostic scan and clearing a fault code?
Clearing a fault code removes the warning light but does nothing about the underlying fault. A full diagnostic scan reads live sensor data, fault history, and ECU module information to identify what has actually failed — which is the only way to carry out a repair that lasts.
Will you be able to fix the fault during the same visit?
In many cases, yes. If the fault is a sensor, pump, or injector failure we can repair on-site, we'll carry out the work during the same visit once we've explained the findings and agreed the repair. More complex issues may require a follow-up visit or parts to be ordered.
My AdBlue warning came back after a top-up — what does that mean?
It means there is an underlying component or software fault that a top-up won't fix. The warning returning shortly after filling the tank is a clear sign something in the system has failed and needs to be properly diagnosed and repaired.
How long does a diagnostic visit take?
Most diagnostic visits take between 45 minutes and an hour and a half, depending on the vehicle and the complexity of the fault. We'll give you a better estimate once we know your make and model.
